Lattice energy is the energy change when an ionic compound is separated into its gaseous ions. It is given in units of kilojoules per mole. For example, when solid sodium chloride is separated into gaseous sodium and chlorine ions (), the lattice energy is 786 kJ/mol.

Lattice energy is the energy released when the gaseous ions form ionic crystal (forms crystal latticei.e 3 dimentional arrangement of diff ions so that there isminimum repulsion between like ions & maximum attraction bet unlike ions leading to lower energy system & maximum stability .L.E is directly prop to couloumbic force bet ions & inversely prop to distance bet them it is measured using Born HABER CYCLE.More is L.E more is stability of ionic comp
